How Tungsten Electrode Grinding Helps Improve TIG Weld Quality

In Booth B37049, COB Industries Inc. (Melbourne, FL) will display the new TEG-1000 Tungsten Electrode Grinder from Huntingdon Fusion Techniques (HFT; Carms, UK). TIG welding requires tungsten electrodes to have perfectly ground and polished tips. Ensuring that these electrodes are sharpened correctly can help to improve weld quality. Tungsten electrode grinders are a convenient, safer and accurate way than other methods of grinding. The TEG-1000 grinder provides repeatable tungsten electrode points every time, enabling consistent, repeatable arc performance and welding results. Sizes 1.0 mm to 3.2 mm can be ground as standard, with other sizes catered for on request. Savings can be achieved because of the increased life of properly ground tungsten electrodes.

With the special collet accessory, shorter electrodes can be held, significantly increasing the length of life of each electrode before it is discarded. The TEG-1000 provides these, time after time, to exactly the same size and shape. The diamond wheel grinds the electrode longitudinally, preventing arc flicker or wander caused by circumferential lines or ridges found on electrodes that have been ground incorrectly. With ground and polished tungsten electrodes, mechanized welding can produce identical, repeatable results every time. With manual welding, the shape of the tungsten electrode is just as important. With a correctly shaped tip, the arc can be precisely positioned with none of the preferential arcing experienced when using poorly shaped manually ground tips.
